Fallout 4 Settlements to Towns (Setters Supplement)

So I just purchased the Settler’s Supplement for Fallout 2d20 and it’s a direct TTRPG conversion of Fallout 4.

Nothing intrinsically wrong with that, but I was hoping it would have rules for larger towns. What’s in the book is good if you’re creating a small clan of 10-20ish people, but what if I wanted to create the Den, for example?

Thoughts about scaling?
